NASA Tests Limits of 3-D Printing with Powerful Rocket Engine Check

Radical changes to the way we do business in Aerospace will drive the next generation of space exploration. Leveraging additive manufacturing to modify the design of a rocket engine injector from 115 parts to 2, is IT!Bear in mind, selective laser melting is not your standard, "buy a $1000 desktop 3D-printer and make a rocket engine", but innovative technologies such as these will eventually make space travel realistic.Great job Marshall Space Flight Center for working this research project.
